I have a Samsung Galaxy S5 with Lollipop and recently broke my screen so that it is now black. adbcontrol worked somewhat okayish - I did not see the whole screen but it was just enough to navigate to my memos and share them. But now I remembered that I hadn't synced my Browser bookmarks so I started my PC again, connected the phone,
adb devices showed the device - but unauthorized.
That already happened to me once so I ran
adb kill-server && adb start-server but the phone stays unauthorized. Unplugging and putting it back in or restarting the computer did not help either.
Why is it suddenly unauthorized? And why can't I fix it with what I tried - because that worked already a few times... And most importantly: Has anybody got any idea how I could make this work again (or maybe a different screen-replacing tool that doesn't require adb) ?
